Google faces UK scrutiny over new advertising data revamp

LONDON — Google faces fresh regulatory scrutiny in Britain over plans to revamp its ad data system, after an industry lobbying group complained to the competition watchdog that the changes would cement the U.S. tech giant’s online dominance.

Marketers for an Open Web, a coalition of technology and publishing companies, said Monday that it’s urging the U.K. competition watchdog to step in and force Google to delay the rollout of its “privacy sandbox” scheduled for early next year.

The new technology would remove so-called third party cookies that allow users to be tracked across the internet by storing information on their devices, replaced by tools owned by Google. That means login, advertising and other features would be taken off the open web and placed under Google’s control, the group said.

The Competition and Markets Authority confirmed it received the complaint.

“We take the matters raised in the complaint very seriously, and will assess them carefully with a view to deciding whether to open a formal investigation under the Competition Act,” it said in a statement, adding that if the concerns need urgent attention, it would consider using “interim measures” to stop any suspected anti-competitive conduct pending a full investigation.

The complaint follows up on concerns about Google’s new system that the watchdog raised in a July report about online platforms and digital advertising. The report recommended the British government adopt a new regulatory approach to governing digital giants making big money from online ads.

Google said the new technology will increase privacy for users while also supporting publishers.

“The ad-supported web is at risk if digital advertising practices don’t evolve to reflect people’s changing expectations around how data is collected and used,” the company said.

Google’s Chrome is the world’s dominant web browser, and many others like Microsoft’s Edge are based on its Chromium technology. Google controls more than 90% of the U.K.’s 7.3 billion-pound ($8.8 billion) search advertising market, the CMA said in its July report.

Third-party cookies allow ad buyers to more effectively target their ads to web users. Privacy sandbox will deny publishers access to the cookies they use to sell digital ads, which will crimp their revenues by up to two-thirds, Marketers for an Open Web said.

The group said Google’s changes will move the digital ad business “into the walled garden of its Chrome browser, where it would be beyond the reach of regulators.” It wants a delay until authorities come up with long term remedies to mitigate Google’s dominance over key parts of the web.
